Arduino Code

This code was created by combining the two codes from the two websites listed below. The code did not work however.

Simple Hit Counter Sketch

Link 1: Hit Counter Arduino Sketch

This sketch is for a counter that counts every time a button is pressed. It displays the number on an LCD screen.

Vibration Sensor

Link 2: Piezo Vibration Sketch

This sketch is for the vibration sensor to light up an LED light.

Arduino Code:

Our code below displayed "Counts: 0" but the sensor did not cause it to count as we planned. 

// include the library code:

#include <LiquidCrystal.h>

// initialize the library with the numbers of the interface pins

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

//creates starting point for counter

int counts = 0; 

//defines the pin connections

const int GroundPin= 1;

const int sensePin= 2;

//defines normal and threshold voltage levels

const int threshold= 250;

//variable to hold the value of sensePin

int senseState = 0;

//variable to hold previous value of the sensePin

int prevsenseState = 0;

void setup() {

  Serial.begin(9600);  

  pinMode(GroundPin, OUTPUT);

  digitalWrite(GroundPin, LOW);

  

  // set up the LCD's number of columns and rows:

  lcd.begin(8, 2);

  // Print a message to the LCD.

  lcd.print("Count: ");

}

void loop() {

  // check the status of the sense

  senseState = digitalRead(sensePin);

  int reading= digitalRead(sensePin);

  //compare the senseState to its previous state

  if (senseState != prevsenseState)

 Serial.println(reading);

  if (reading > threshold) {

  counts = counts + 1;

  }

  // set the cursor to column 0, line 1

  // (note: line 1 is the second row, since counting begins with 0):

  lcd.setCursor(0, 1);

  // print the number of counts:

  lcd.print(counts);

}
